R. Silva" To: Richard Cochran , Andrew Lunn , Florian Fainelli , "David S. Miller" Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case, I replaced the code comment at the top of the switch statement with a proper "fall through" annotation for each case, which is what GCC is expecting to find.
